Another common desalination process is Reverse Osmosis. It involves a solvent passing through a semi-permeable membrane; meaning this particular membrane only allows some molecules to penetrate or pass through. The solvent will then go into a solution with higher concentration of molecules.
Most genetically engineered fish are used in basic research in genetics and development. Two species of fish, zebrafish and medaka, are most commonly modified because they have optically clear chorions (shells), rapidly develop, and the 1-cell embryo is easy to see and microinject with transgenic DNA.ome GM fish that have been created have promoters driving an over-production of all fish growth hormone. This resulted in dramatic growth enhancement in several species, including salmonids, carps and tilapias.
A GMO (genetically modified organism) is the result of a laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal. The foreign genes may come from bacteria, viruses, insects, animals or even humans.Because this involves the transfer of genes, GMOs are also known as âtransgenicâ organisms. This process may be called either Genetic Engineering (GE) or Genetic Modification (GM); they are one and the same.
